I purchased these online. This is a set of 4. I used these as play clothes for my son at daycare. My son is 1.5 years old, but he is muscular and quickly outgrew them. The size is 90, but they feel small. The elastic in the waist isn't very loose. They are 10-分丈 (ten-minute length, meaning they are full length). [Black] → Slightly brownish black. Worn about 5 times. Some slight pilling. Not very noticeable. [Brown] → Worn about 5 times. Some slight pilling. Not very noticeable. [Light Blue] → Worn less than 3 times.

In good condition. *There may be some stickiness because I had name stickers on the tags.
